Hi all,

I have been running a competing risk regression for my study. I carried out the analyses using stepwise adjustments for confounders, and the first two adjustments worked perfectly. However, in my fully adjusted model, I am getting a strange error (screenshot attached). Anyone have any idea what's going on here? It is EXACTLY the same model I have run for previous competing risks regression, just with an extra few confounders in the model. I have no idea what could possibly be going on here.

Code below. As mentioned, the first two commands are working perfectly and the output is what I'd expect. I am getting the error on the third and final adjustment. I would like to know what's happening before running the code again, as it takes a long time to execute.

Code:
stcrreg timetofbetablockerana, compete(otherdeath==1)
stcrreg timetofbetablockerana i.catdateofdiag i.newage i.ethnicgroup i.deprivation i.urban i.pubprinew i.regnew i.stage_grp i.newgrade i.screendetectednew i.lvi i.receptorstatusnew, compete(otherdeath==1)
